Answer:
x=26
Step-by-step explanation
Remember the Law/Proof that the sum of the angles in a triangle is 180 degrees.
<u>My very Simplified equation:</u> 7x-2=180--->182/7=x so x=26
Use that rule and good luck on the rest:3
Answer:
y=57 degrees and x=66 degrees
Step-by-step explanation:
123+57 =180 so angle y=57 degrees
57+57=114 all triangles = 180 degrees so 180-114=66 degrees=X
Answer:
C) 80
Step-by-step explanation:
x + 80 + 20 = 180
x + 100 = 180
x = 80
The answer would be 20
A squares sides are equal and there are 4 of them so you take 80 (the total perimeter) and divide that number by 4 (number of sides) and you get 20
